realme 12 5G (RMX3999) Review: A Comprehensive Look at the Twilight Purple 8GB/256GB Model

Introduction
The realme 12 5G (RMX3999) arrived on my desk promising a compelling blend of performance and affordability. This review dives deep into my experience with the Twilight Purple 8GB RAM + 256GB storage variant, exploring its strengths and weaknesses after weeks of rigorous testing.
Features
The realme 12 5G boasts a sleek design and a vibrant 6.72-inch IPS LCD display with a 1080×2400 resolution. The Twilight Purple color is undeniably eye-catching. The 5000mAh battery, coupled with 45W SuperVOOC fast charging, consistently delivered excellent battery life, often lasting a full day and more on moderate use. The dual rear camera system, featuring a 108MP primary lens and an 8-11.9MP secondary lens, offers decent image quality, especially in good lighting conditions. The MediaTek Dimensity 6100+ processor, combined with 8GB of RAM (expandable to 16GB via DRE technology), ensures smooth multitasking and a responsive user experience. The inclusion of Android 14 out-of-the-box is a significant plus.
Performance
Day-to-day tasks, from browsing the web to using social media, were handled flawlessly. The Dimensity 6100+ processor proved capable of handling demanding games like Call of Duty Mobile with minimal lag at medium settings. The fast charging capabilities are genuinely impressive; a 1-50% charge in 30 minutes consistently lived up to its claim. However, heavy gaming sessions did noticeably drain the battery, although this is expected. The cameras delivered passable image quality, though detail suffered in low light. The 256GB of internal storage was more than ample for my needs.
Pros & Cons
Pros:
- Stunning Twilight Purple design
- Excellent battery life and 45W fast charging
- Smooth performance thanks to Dimensity 6100+ processor and ample RAM
- Large, vibrant display
- Latest Android 14 operating system
- Ample internal storage
Cons:
- Camera performance could be improved in low-light conditions
- IPS LCD panel, not AMOLED, so colors are not as vibrant
- Gaming at high settings may cause noticeable heating
Final Verdict
The realme 12 5G (RMX3999) offers an impressive value proposition. Its fast charging, excellent battery life, and smooth performance make it a strong contender in its price range. While the camera could use some improvements, the overall experience is positive. I would wholeheartedly recommend this phone to anyone looking for a reliable, feature-packed 5G device without breaking the bank.
